ISAAC DAVID WRIGHT, OF SEDALIA, MISSOURI, ASSIGNOR OF ONE-HUN- DRED-AND-ELEVEN ONE-HUNDRED-AND-TWELFTHS TO 0. O. VAN WAG- NER, W. H. VAN WAGNER, AND R. H. MOSES, OF SAME PLACE.

SHOE-FASTENER.

SPECIFICATION forming part of "Letters Patent No. 540,937, dated June 11, 1895.

Application filed May 14, 1894.

To all whom it may concern:

Be it known that I, ISAAC DAVID WRIGHT, of the'city of Sedalia, Pettis county, State of Missouri, have invented certain new and useful Improvements in Shoe-Fasteners, of which the following is a full, clear, and exact desoription, reference being had to the accompanying drawings, forming apart hereof.

This invention relates to, and isan improvement on, my invention described and claimed in application for United States Letters Patent filed April 9, 1891, and since patented, No. 526,956, dated October 2, 1894.

Referring to the drawings, Figure 1 is a perspectiveview ofa low shoe having my at- Fig. 2 is a perspective view of a portion of a modified form of my device. Fig. 3 is a perspective view of a portion of a further modified form of my device and a clamp which fastens the same to the shoe. Fig. 4 is a perspective view of the top portion of a low, shoe or slipper anda modified form of my device applied thereto. Fig. 5 is a side elevation of the lower portion of a modified form of spring clamping device. Fig. 6 is a side elevation of the device used to attach the spring-clamp to the shoe or overshoe, Fig. 7 being a perspective view'of the same. Figs. 8 and 9 illustrate hooks or 1oops fastened to the rear upper portion of the shoe and adapted to retain the clamping-loop down, as shown in Fig. 4, and notin contact with a persons shoe or heel.

In the construction of the device as shown, the numeral 1 designates a shoe and 2 a spring-frame secured thereto. This spring frame comprises a body portion 3, which is semi-circular in plan view. and having the loop 4 in the center thereof The two portions 5 and 6 of the body portion 3 pass downwardly to each side of the top portion of the shoe, are there clamped .by a device yet to be described; passed forward, bent into the convolute portions 7; passed rearwardly in a plane above the clamping device, and looped around the portions 5 and 6 as designated by the numerals 8 and 9. When the semi-circular portion 3 of the frame 2 is depressed into the plane of the top edge of the side and rear portions of the shoe, it will embrace the Y is composed of two parts 31, 32.

Serial No. 511,097. (No model.)

rear portion of said shoe and be out of the plane of entrance of the foot into said shoe, as is required to permit the positioning of the shoe relative to the foot. The resilience of the convolute portion 7 communicated to the semi-circular portion 3 through the rear- Wardly extending portions and loops 8 and 9, causes the semi-circular portion 3 to reassume a position in the rear of, and above, the heel of the wearer after the downward pressure thereon is released, thus firmly connecting the shoe to the wearer by the engagement of said frame with the upper and rear portion of the heel.

In the construction of the device shown in Fig. 2 the spring and clamp are formed of a single piece of wire 23, the rear semi-circular portion 24: of which is waved. The side portions 25, 26 extend forwardly, thence into convolute portions 27, thence rearwardly, and are clamped to the upper and rear sides of the low shoe, slipper, or overshoe.

In the device shown in Fig. 3 said device is composed of a single piece of wire 28, which, after extending downwardly and forwardly, is bent rearwardly and upwardly, designated by the numeral 29; thence forward into loops 2 9 around the body portion. The clamp specially formed, surrounds the upwardly and rearwardly bent portion 29, thereby clamping the spring frame to the shoe.

In the device shown in Fig. 4 the clamp 30 The part 31 at its forward end is looped around the spring clamp 30, extends forwardly and bent into the semi-circular portion 32, and then extends rearwardly terminating in the longi-- tudinal portion 33. The part 31 is, at its forward end, looped around the body portion 'of the part 31, extends rearwardly, bent into the semi-circular portion 34, and then forward into the longitudinal portion 35. A clamp surrounds the parts 33 and 35 and securely holds the springs to the outer sides of the shoe,

rubber, or overshoe. The lower ends of the spring-clamp 3O terminate in eyes or loops which are secured to the shoe by means of common staples or stitches.

In the construction of the device shown in Fig. 5 the spring and clamp are formed of a single piece of wire, the lower ends of which are bent into the loop 36, thence forwardly into the convolute portion 37, thence rearwardly and upwardly terminatingin the loop 38, surrounding the main body portion.

Referring now to Figs. 6 and 7, in which is shown the metal clip, or clamp, by means of which the various forms of springs and clamps are attached to the shoe, this clamp is formed of a rectangular portion of sheet metal 39 having at each corner thereof, the attenuated portions 40. In double alignment of the body portion 39 are the triangular perforations 41. The triangular portions 42 that protrude from these triangular perforations 41 are adapted to be clamped around, and securely hold, the end portions of the springs, or clamps, as may be desired. By passing the attenuated portions 40 through the leather, rubber, or other material from which the shoe may be formed and upsetting the same on the inner side of the shoe, slipper, or overshoe, said clamps 39 may be securely held to said shoe. The hooks shown in Figs. 8 and 9 are of great utility. in holding the clamping-loop down out of contact with the operators shoe whenever the operator does not wish to feel the pressure caused by said clamping-loop upon his foot, and were it not for said hook,

this pressure would in some cases become inconvenient and irritable, but by drawing the clamping loop down and causing it to engage beneath said hook, as shown in Fig. 4, all such objections will be overcome.

What I claim is- 1. A clamp for securing springs and frames to shoes orovershoes, comprising a rectangular body portion having attenuated portions extending therefrom, and double rows of triangular integral portions extending therefrom in longitudinal alignment, in combination with a spring-wire frame held in place by said clamp, substantially as specified.

2. The combination with ashoe, of a clamping-frame yieldingly mounted upon the rear portion thereof, springs attached to said shoe and acting upon said clamping frame, and a securing hook attached to the upper rear portion of the shoe and adapted to retain the clamping frame in an inoperative position, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
